void InitGoertzel(void)
作用:初始化算法参数
用法:采用算法进行检测前执行一次,如果需要改变参数,调用SetParameter(...
void InitGoertzel(void)
作用:初始化算法参数
用法:采用算法进行检测前执行一次,如果需要改变参数,调用SetParameter()
float CGoertzel::GetMagnitude(unsigned char * sampleData, int length) //算法主接口
作用:对采集下来的音频数据用算法处理,返回一个结果
参数:sampleData-音频数据缓冲地址指针;
length-缓冲区尺寸(音频数据数量),字节数;
返回值:返回算法结果。
void SetParameter(DWORD set_SampleRate, DWORD set_TargetFreq, DWORD set_BlockSize)
作用:设置算法参数;
参数:set_SampleRate-音频数据抽样速率;
set_TargetFreq-目标信号频率;
set_BlockSize-算法数据块尺寸(采样点);
用法:调用本函数后,需要调用一次InitGoertzel(void)才会生效-void InitGoertzel (void) function: initialization algorithm parameters Usage: The algorithm performs a pre-test, if the need to change the parameters, calling SetParameter () float CGoertzel:: GetMagnitude (unsigned char* sampleData, int length)// Algorithm for the main interface role: to collect audio data from the treatment algorithm to return a result parameter: sampleData-audio data buffer address pointer length-buffer size (the number of audio data), number of bytes return value: the return of
